Which quasi-sine wave inverter is better
Quasi sine wave inverters are far cheaper and some appliances will work perfectly well but others may not; as a general rule if you are planning on running basic electrics then a modified sine wave inverter should be fine but for any more sophisticated or sensitive equipment you should use a pure sine wave inverter which produces an output akin to normal AC.

FAQS about Which quasi-sine wave inverter is better
What are the advantages of a pure sine wave inverter?
A pure sine wave inverter has several advantages over its previous two forms: More efficiency, hence consumes less power. They can be adjusted according to your personal power requirements, since several types are available with different power outputs.
What is the difference between a sine wave and a square wave inverter?
A sine wave inverter/UPS can produce power that is of a higher quality and is more suitable for sensitive electronic equipment. In contrast, a square wave Inverter is less expensive and is better suited for powering motors and other types of load that are less sensitive to waveform distortion.
What is a sine wave inverter?
A power inverter device which produces a multiple step sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three step) inverter designs, the manufacturers often use the phrase pure sine wave inverter.
Does a sine wave inverter produce a smooth sine wave output?
Almost all consumer grade inverters that are sold as a "pure sine wave inverter"do not produce a smooth sine wave output at all, just a less choppy output than the square wave (two step) and modified sine wave (three step) inverters. However, this is not critical for most electronics as they deal with the output quite well.
What is the difference between a sine wave inverter and a ups?
The main difference between the two types of inverters is their power quality. A sine wave inverter/UPS can produce power that is of a higher quality and is more suitable for sensitive electronic equipment.
Does a sine wave inverter convert DC to AC?
However, an inverter/ups convert DC to either square wave or sine wave AC at the core of its circuits. The output of a sine wave inverter is remarkably similar to AC. The sine wave output is purer than the square wave output, which is also the basis for the phrase “pure sine wave inverter/ups.” What is a Sine wave inverter/UPS?
